Glenn Cooper handles complex business, financial, commercial and domestic litigation involving significant business issues in Maryland and the District of Columbia. He appears before federal and state courts at both the trial and appellate levels, and before arbitration panels and professional disciplinary boards.

Glenn’s personal philosophy is to “be honest, be kind (when possible), be persistent, be bold” — an approach that has led to countless favorable outcomes for his clients and to him having an outsized impact on his industry.

A number of Glenn’s cases have helped shape the current state of the law in a number of areas. He is among a select group of active lawyers who have briefed and argued multiple civil cases in Maryland’s Supreme Court, the state’s highest court. Glenn has earned the respect of his colleagues, having represented a number of lawyers and law firms in Montgomery County. He lectures before various legal and professional associations, and has authored many articles on business issues.

Glenn is a Fellow of the American College of Trial Lawyers (membership is exceptionally selective and by invitation only) and a Fellow of the American Academy of Matrimonial Lawyers, a national organization whose members are recognized for maintaining the highest degree of professionalism, integrity and excellence in the practice of family law. He is one of about 30 attorneys in the state of Maryland to be named to this prestigious group. Glenn is admitted to practice before a variety of federal and state courts, including the U.S. Supreme Court.

Glenn was selected as the number one attorney in all of Maryland for four out of the last five years by Maryland Super Lawyers. He was selected as the number two attorney in the State the other of the last five years. Glenn is also listed as being in the Top 10 Super Lawyers in the District of Columbia and is currently the only attorney in the United States listed on Top 10 Super Lawyers lists in more than one jurisdiction.

Glenn takes great pride in being a husband, a father of three, and a grandfather of six. In his free time, he likes to hike, bike, read, check out live music, travel, spend time outdoors, and root for the Terps.
